British supermarket chain Sainsbury’s has unveiled new sustainable cardboard packaging for all its own-brand liquid laundry detergent.

Available starting this week in all stores and online, the new laundry liquid detergent packaging is designed to help customers reduce plastic at home.

The packaging will replace the previous sleeved plastic bottle packaging across all Sainsbury’s own-brand 750ml laundry detergents with cardboard cartons.

The own-brand laundry detergents include tropical super concentrated laundry liquid, bio super concentrated liquid, colour super concentrated liquid, lavender super concentrated liquid and non-bio super concentrated liquid.

According to the retailer, customers can easily recycle the packaging at the kerbside or deposit the packaging at recycling banks.

The new cardboard cartons are expected to save around 22 tonnes of plastic every year, reducing the use of plastic by 80%.

Sainsbury’s said that the packaging is made from cardboard certified by the Forest Stewardship Council (FSC).

Additionally, the cartons are 35% lighter than the original packaging and will minimise the carbon emissions of this product range by 50%.

This is equivalent to emissions from 13 lorries during packaging transportation annually, the firm said.

Sainsbury’s has also made the laundry detergent more concentrated by reformulating it so that a smaller amount of detergent is required per wash. This will allow for five additional washes per carton.

The transition move is anticipated to help the supermarket chain to achieve its goal of net-zero emissions across its operations by 2035.

The retailer said the new packaging is also part of its commitment to halve its use of its own brand plastic packaging by 2025.

To achieve this, Sainsbury’s introduced a range of packaging changes like the launch of its 1L reusable handwash pouches last year that uses 85% less plastic than identical bottles, remove 28 tonnes of plastic annually, and are 35% less expensive.

Furthermore, the company introduced double-length toilet paper rolls, which reduced plastic packaging by 30% and saved 84 tonnes of plastic.
